If I use autoIP together with dhcp.client and a DHCP server is able to provide an IP address I also get an alias address from autoIP. I end up with two accessable IP addresses. Is there any way to run dhcp.client so I don't end up with the autoIP alias? This is on a 6.4.1 system.
I've found that I can detect the alias address and delete it using ifconfig en0 delete 169.254.20.20 and I no longer have the alias (169.... is an example IP alias address). However, the alias comes back after a while. Who is generating the alias -- the auto-ip driver or the dhcp.client?
